Pipe tapping saddle

Abstract

A pipe tapping saddle for a main pipe having a center axis and conveying a medium. The pipe tapping saddle includes a saddle piece; a branch pipe having a center axis, a drill socket having a center axis, and a drill with a thread being arranged displaceably in the drill socket for tapping the main pipe. The pipe tapping saddle is arranged on the main pipe. A center axis of the branch pipe runs horizontally and is arranged below an upper crown point of the main pipe.

What is claimed is: 
     
       1. A pipe tapping saddle for a main pipe having a center axis and conveying a medium, the pipe tapping saddle comprising:
 a saddle piece; 
 a branch pipe having a center axis, 
 a drill socket having a center axis, 
 a drill with a thread being arranged displaceably in the drill socket for tapping into the main pipe, 
 wherein the pipe tapping saddle is arranged on the main pipe, 
 wherein the center axis of the branch pipe runs horizontally and is arranged below an upper crown point of the main pipe, 
 wherein the center axis of the drill socket is oriented perpendicularly to the center axis of the main pipe, and 
 wherein the center axis of the drill socket intersects the center axis of the main pipe at a right angle. 
 
     
     
       2. The pipe tapping saddle according to  claim 1 , wherein an upper crown line of the branch pipe is arranged below the upper crown point of the main pipe. 
     
     
       3. The pipe tapping saddle according to  claim 1 , wherein the center axis of the drill socket is arranged at an angle α<90° to the center axis of the branch pipe. 
     
     
       4. The pipe tapping saddle according to  claim 1 , wherein the center axes of the drill socket and the branch pipe are arranged on a plane, wherein the plane is arranged at a right angle to the center axis of the main pipe. 
     
     
       5. The pipe tapping saddle according to  claim 1 , wherein the center axis of the branch pipe extends through a borehole drilled through the main pipe by the drill. 
     
     
       6. The tapping saddle according to  claim 1 , wherein the saddle piece has a drill opening, wherein the center axis of the branch pipe extends through the drilling opening. 
     
     
       7. The pipe tapping saddle according to  claim 1 , wherein the center axes of the drill socket and the branch pipe extend within a plane and intersect in a region of an internal diameter of the main pipe. 
     
     
       8. The pipe tapping saddle according to  claim 1 , wherein sealing during the tapping is ensured in the drill socket by means of a seal, and wherein the seal is arranged on an internal diameter of the drill socket. 
     
     
       9. The pipe tapping saddle according to  claim 8 , wherein the seal is designed as a plastic diaphragm which closes off the drill socket before the plastic diaphragm is drilled through with the drill and after being drilled through, the plastic diaphragm provides a seal between the drill socket and the drill. 
     
     
       10. The pipe tapping saddle according to  claim 8 , wherein the seal is an O-ring or a profile seal. 
     
     
       11. The pipe tapping saddle according to  claim 6 , wherein the drill opening corresponds to a drilling diameter of the drill.
